TO ALL WHOM IT MAY CONCERN:

Be it known that I, ELIPHALET S. SonIPrn'nE, of Brooklyn, Kings county,New York, have invented certain new and useful Improvements inCarriage-Tops, for the convenient mode of constructing, handling, mangg, and governing the same; and I do declare the following to be a full,clear, and correct description of my said invention, reference being hadto the accompanying drawings, making partof this specification, and tothe letters of reference marked thereon, in which---- 7 Letter X showsan oblique elevation of the whole seat and top.

Figure 1 shows a side elevation of the inner disk of the female half ofthe main'or bow-joint, with its standard or base.

-Figurefl, the same view of the male half of the same. Figure 3, an edgeview of the male half, with its horizontal belt or shaft passingthrough. Figure 4, a fiat view of. one-half ofan extonsion-joint. vFigure 5, a side elevation of the handle-nut to the main joint. In thedrawings, likeparts of the invention are designated by the same lettersof reference.

The nature of my invention consists in the use or employment of circularfrict ionsurfaccs, constructed. as

hereinafter described, for the purpose of raising, lowering,controlling, and securing a carriage-top in the varione forms. andpositions required.

To enable those skilled in the arts to make and usemy invention, I willdescribe it, as follows:

Letter X shows a plain carriage-seat, upon each arm or end of which aresecured the main bow-joints, when the parts A B, B 2', and G G arecombined, letter a,'the back or main how, (as being attached to theouter surface of the male or revolving wedge-circle,) and represented ashaving been turned back flat down; at, the middle how, and a 2' 2', thefront'bow, the two being elevated and secured in position by means ofthe joint E and H, having been extended, and thus secured by means oftho thumb-screwF.

To drop the bbws a 2' and a c' 2', turn backward thumb screw F, whenthey may be dropped entirely, or partially, and there secured firmly bydrawing together the fruition-disks A and B by means of tliurnh-screw F.When the whole top is elevated, the main or baekbow is held in positionby means of the handle screw-nut, letter D, being screwed upon the shaftG O, as shown at D c', in letter X, where also may be seen the twoconnecting bow-straps i and j, which connect and secure the three bowstogether, (or four, if that number is used.)

The main or back bowie firmly sustained and held in place by means ofthe powerful cohesive attraction of the wedge-surfaces, as a substitutefor the outside back braces on an ordinary carriage-top, which how hasalso to sustain the other portion of the top in its position, to whichmain or back bow is attached one end of the joint-brace E and H, whilethe other end is attached by pivot to the front how a i z. The saidbraces E and H may he used by placing one at each side of the top, or asingle one at the top, to eifect the extension. thereof.

The advantages possessed by my present invention are- First. Simplicityand small cost of construction, in view of the many and importantresults derived therefrom.

.Second. Greater strength, when properly made.

Third. The readiness with which the whole top may be taken oil" andagain replaced, and I Fourth. That the folds may be readily placed andfirmly held at any chosen point, while being operated from inside,thereby quickly laying back the front bows while another person getsinto the seat, and as readily replaced thereafter.

Fifth. By means of the main bow-joint A and B, the greaterportion of theweight of the bows and top may he sustained, without resting wholly uponan arm or horn, therebypreventing all jouncing, rattling, and chafing.

Sixth. That the main bow-joint may he set upon the seatrarms, with thebows either inside or outside, allowing the handle-nut D to do itsoffice on either side, convenient to be got at while sitting inside,while at the same time presenting facilities for ornamentation eitherinside or outside.

Claim.

Having thus described my invention, what I claim as new, snd desire tosecure by Letters Patent, is not the circular corrugated wedgefriction-surfaces as when made by themselves, as the same has been madeby me, and described in mypatent, dated January 7, 1868, for compasses,calipers; 860.; but

I wish to claim their application, as described, when combined with acarriage-seat and top, substantially I in the manner and for thepurposes set forth.
